CAR-ROOF..

SPECIFICATION forming part of Letters Patent No. 582,160, dated May 4, 1897.

Application filed August 26,1896. Serial Noy 603,977. (No model.)

To @ZZ wwm it may concern.:

Be it known that I, Josnrn L. HoNnonsT, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Oar-Roofs; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in car-roofs, and is de signed more particularly for use in connection with freightcars.

The object of my invention is io so co-nstruct the roof of a freight-car that all danger of leaking will be entirely overcome and si1nple and improved means provided for readily and quickly conducting off any and all moisture that may percolate through the wooden protecting-roof and accumulate around the joints of the interior rooiingplates- In carrying out my invention I provide the joists of the car-roof with grooves or gutters in their top surfaces. The metallic roofingplates are designed to be supported by said joists and have their edges turned down into said grooves or gutters, where they are secured in position by suitable strips fitting in said grooves or gutters, a space being formed between the top surfaces of thelatter and the bottom faces of said strips, whereby conduits are formed for conducting away any moisture that may percolate through the usual wooden rooling, which is supported by said strips.`

The invention will be hereinafter fully set forth, and particularly pointed ont in the claims.

In the accompanying drawings, Figure l is a View in perspective illustrating a portiony of a car-roof constructed in accordance with my invention. Fig. 2 is a sectional view thereof. Fig. 3 is a detail perspective View of one of the joists. Fig. 4 is a similar view of one of the securing-strips. Figs. 5 and C are views of slightly-modiiied forms of the latter.

Referring to the drawings, A designates a freight-car, and a the transverse]y-arranged" joists for supporting the roof thereof. Said joists are secured to the car-body in the usual or any preferred manner, and are provided with central longitudinal grooves a', having a central raised portion or ridge a2, the sides of said grooves being preferably flared, as shown. The roofing-plates B are formed of sheet metal and have their edges b bent downi ward, so as to rest against the sides a3 of groove a'.

C designates the securing-strips, which are each preferably formed with tapering sides d, designed to fit in the grooves a' and against the edges b of the roofing-plates. Said strips are secured in position by any suitable means and their lower faces rest on the central ridges a2, forming conduits or passage-ways for conducting oif rain or any moisture which may happen to leak through the joints of the ordinary wooden rooiin g O', which is supported by said strips O. In this way moisture is prevented from penetrating to the interior of the car.

In lieu of forming the central ridges c2 in grooves or gutters a' grooves or cnt-outs I) may be formed in the under faces of .securingstrips O, as shown in Fig. 5, or the beveled faces of said strips may be provided with grooves or cut-outs d', as shown in Fig. 6.

The advantages of my invention are apparent from what has been said. It will be specially observed that all leakage to the interior of the car is entirely prevented thereby, and that the plates serve to rigidly imite the joists together, and all strain lengthwise of the car is obviated, as well as danger of the parts pulling loose.

I claim as my invention- 1. The combination with a ear-body having roof-j oists provided with longitudinal grooves or cut-outs, of strips secured in said grooves or cut-outs, spaces being formed between said joists and said strips and serving as conduits or passage-ways for moisture, as set forth.

2. The combination with a car-body having roof-joists provided with grooves in their top surfaces, of roofing-plates having their side edges resting on said joists, and securing strips secured to said joists and overlapping the edges of said roong-plates, spaces being formed between said joists and said strips and serving as conduits or passageways for moisture, as set forth.

3. The combination with a car-body having roof-joists provided with longitudinal grooves IOO or eut-outs having a central ridge, of roofingplates having their side edges resting in said grooves or eut-outs,zmd securing-strips fitting in said grooves or eut-outs, as set forth.

4. The combination with zt ear-bodyhaving roofjoists, said joists being provided with grooves or eut-outs the sides of which are beveled or flared, t central ridge being formed between said grooves or out-outs, roofingpiates'having their side edges turned down in said grooves or eut-outs and resting against f 582,1 eo

the sides thereof, and securing-strips of taper'- ing forni fitted in said grooves or eut-outs, as and for the purpose set forth.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.

JOSEPH L. HONHORST.
